Genes affected
POT1 (HGNC:17284): (protection of telomeres 1) This gene is a member of the telombin family and encodes a nuclear protein involved in telomere maintenance. Specifically, this protein functions as a member of a multi-protein complex that binds to the TTAGGG repeats of telomeres, regulating telomere length and protecting chromosome ends from illegitimate recombination, catastrophic chromosome instability, and abnormal chromosome segregation. Increased transcriptional expression of this gene is associated with stomach carcinogenesis and its progression. Alternatively spliced transcript variants have been described.

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Aug 04, 2021 | ClinVar contains an entry for this variant (Variation ID: 475021). For these reasons, this variant has been classified as Pathogenic. This variant has not been reported in the literature in individuals affected with POT1-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Pro383Metfs*10) in the POT1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in POT1 are known to be pathogenic (PMID: 32155570). - |
